Remember:
a) (x,y) => (x, -y) is a reflection across X axis
b) (x,y) => (-x,y) is a reflection across Y axis
Here △RST is mapped to △R′S′T′ using the rule (x,y)→(x,−y)
Hence it is a reflection across X axis.
The size of the triangle does not alter.
But when this is followed by (x,y)→(3x,3y), the lengths increase by a factor 3.
Hence the triangles do not remain congruent.
△RST is not congruent to △R′S′T′ because the rules do not represent a sequence of rigid motions.
Option A) is the right answer
7. plot the points and then measure the height and base
then find the area of parallelogram 1/2*b*h
8. draw a horizontal line on any point y axis
and then plot r go to 0 and then up one over one repeat the steps and then down one to the right one
No because 1/3(30) would be equal to 10 and 10 is not equal to 15
Answer:
1/4
Step-by-step explanation:
Absolute value is the distance of a value from 0, you can think of it as a number line. So -2/8 is equal to -1/4 when simplified, and -1/4 is 1/4 away from 0 on the number line
Answer:
Step-by-step explanation:
(16). = 3.5 m/min.
(17). = - 11.5 m/min.
